Online Video Converter
EchoWave's video converter runs in your browser and takes MP4, MOV, WebM, AVI and common audio files with nothing to install. Pick an output format, adjust the codec, bitrate and frame rate if you need to, and the cloud render farm handles the encoding, so conversion speed never depends on your hardware. Because the converter lives inside a full editor, you can trim, crop, caption or compress the file in the same pass.
Online Video Converter Features
EchoWave's video converter is used by marketers, teachers, podcasters and support teams around the world.
176 converter pairs
One video converter for every format pair
EchoWave hosts 176 converter pairs, so the exact swap you need almost certainly has its own page, from MOV to MP4 for iPhone footage to WebM to MP4 for screen recordings and video to MP3 when only the audio matters. Upload once, choose an output, and download a file that plays where you need it to. Nothing installs, and nothing depends on your hardware.

Convert, then keep editing
Every conversion runs through the same cloud pipeline as EchoWave's full editor, so these tools come along at no extra step.
-
A video converter inside a full editor
Most converters take a file and hand back a file. EchoWave's converter sits inside a complete timeline editor, so you can trim dead air, crop out a letterbox or compress the file before you pick an output format. One upload covers the whole job.
-
MP4, WebM, MOV and GIF outputs
MP4 export is on every plan because it plays on practically everything. WebM comes with Basic, and MOV plus GIF arrive on Pro. If MP4 is your target, the MP4 converter page covers each input format in detail.
-
Audio outputs: MP3, M4A, WAV and FLAC
Strip the picture and keep the sound. Audio extraction works from any supported input, with MP3 and M4A on Basic plans and lossless WAV and FLAC on Pro. It turns recorded interviews, lectures and webinars into files a podcast app can play. For audio-to-audio jobs, the audio converter page covers each pair.
-
Codec, bitrate and frame rate controls
Pick a codec, set the bitrate and choose the frame rate instead of accepting whatever a converter guesses. Resolution runs from social sizes up to 4K on Pro plans, with 8K and 120fps available on Business.
-
Cloud rendering, so hardware never slows you down
Conversion happens on EchoWave's render farm, not your CPU. A 2019 laptop or a Chromebook converts at the same speed as a new workstation, and your fans stay quiet. The browser only handles the upload.
-
Burn in subtitles while you convert
Auto-generate captions with word-level timing, style them with 176 presets, then hardcode them into the converted file. You can also import an SRT, translate subtitles into 86 languages, or export SRT and VTT files alongside the video.
-
Old and awkward formats included
AVI to MP4 rescues footage from older cameras and Windows archives, and 176 dedicated pairs cover the long tail. If a format refuses to play on a specific device, there is a dedicated page for that exact conversion.
How it works
How to convert a video online
The same four steps work for every format pair, from MOV to MP4 through to video to MP3.
-
Upload your file
Drag a video into the browser or pick it from your device. MP4, MOV, WebM and AVI inputs all work, along with MP3, WAV and M4A audio. There is nothing to install.
-
Edit before converting (optional)
Trim the ends, cut a section from the middle, crop the frame or add captions. Skipping this step is fine, plenty of conversions are plain format swaps.
-
Choose the output format and settings
Pick MP4, WebM, MOV, GIF or an audio format, then set resolution, frame rate, codec and bitrate if the defaults are not right. MP4 with default settings suits most uses.
-
Render in the cloud and download
EchoWave's render farm does the encoding and the finished file lands in your account. Free plans export HD (up to 720p) MP4 with a small removable EchoWave watermark badge, and paid plans remove the badge and raise quality to 1080p up to 4K, with 8K on Business.
Everyday conversions
What people use a video converter for
-
iPhone footage for Windows machines
MOV files from an iPhone or a Mac sometimes stall on Windows PCs and older software. Converting to MP4 makes the clip play anywhere before you send it to a client or colleague.
-
Screen recordings into presentations
Browser recorders often produce WebM, which PowerPoint and some players refuse. A WebM to MP4 pass makes the recording drop cleanly into slides and course uploads.
-
Podcast episodes from video interviews
Record a video call, convert it to MP3, publish the audio feed. WAV and FLAC outputs are there when an audio editor asks for lossless files.
-
Rescuing old AVI archives
Family tapes and early digital cameras left a lot of AVI behind. Converting to MP4 puts those files on modern phones and TVs without a codec hunt.
-
Clips into GIFs for docs and chat
A short MP4 turned into a GIF autoplays in pull requests, Notion pages and Slack threads. GIF export is available on Pro plans.
-
Reformatting for vertical platforms
Convert the format and resize the canvas to 9:16 in the same session, so one horizontal master becomes a TikTok, Reels or Shorts upload.

Based on each tool's public pages as of July 2026. HandBrake gives the deepest encoder control of any free tool, and CloudConvert reads far more file types. EchoWave's case is converting and editing in one browser tab with cloud rendering.
Convert a video without installing anything
Upload a file, pick a format and let the cloud do the encoding. Free exports are HD with a small removable watermark badge, and paid plans remove it and cover downloads up to 4K.

Online Video Converter FAQ
What is the best free video converter?
It depends on where you want to work. HandBrake is the strongest free desktop option, with deep encoder control and no cost at all. EchoWave is the browser route: free HD exports up to 720p with a small removable watermark badge, and it adds trimming, cropping and captions that a plain converter lacks.
How do I convert a video to MP4?
Upload the file to EchoWave, choose MP4 as the output format, and render. MP4 is available on every plan because nearly every device, browser and editing tool accepts it. If your source is MOV, WebM or AVI, the dedicated pages for those pairs walk through the specifics.
Does converting a video lose quality?
It can, because most conversions re-encode with a lossy codec such as H.264. Keep the bitrate at or above the source, match the resolution, and avoid converting the same file repeatedly. A single well-set conversion is usually indistinguishable from the original in normal viewing.
Is it safe to use an online video converter?
Safer than downloading a random converter executable, which is a classic adware vector. With EchoWave nothing installs on your machine, uploads stay attached to your account, and rendering happens on a secure cloud farm. As with any online tool, read the privacy policy before uploading sensitive footage.
Can I convert a video without installing any software?
Yes. EchoWave runs in Chrome, Edge, Firefox and Safari on Mac, Windows, Linux and Chromebooks, and the encoding happens in the cloud rather than on your device. Desktop apps for Mac and Windows exist too, but the browser version is the complete tool.
How do I convert a video to MP3?
Upload the video, choose MP3 as the output, and render. MP3 and M4A are included from the Basic plan, with lossless WAV and FLAC on Pro. The full audio track comes along, so trim the video first if you only need a section.
What formats does EchoWave's video converter support?
Inputs cover MP4, MOV, WebM and AVI video plus MP3, WAV and M4A audio. Outputs are MP4 on every plan, WebM from Basic, MOV and GIF from Pro, and the four audio formats, spread across 176 converter pairs. For rare containers like MKV or FLV, a desktop tool such as HandBrake or a many-format service like CloudConvert is the better fit.
Why do people convert everything to MP4?
MP4 with H.264 is the closest thing video has to a universal format. Phones, browsers, TVs, editing software and every major social platform accept it, and it compresses well at normal viewing quality. Converting an odd format to MP4 once usually ends the compatibility problem for good.
Is EchoWave's video converter free to use?
Yes. The free plan covers uploading, editing, previewing and exporting: free exports are HD (up to 720p) MP4 with a small removable EchoWave watermark badge and a short branded end card. Paid plans remove the badge and raise quality to 1080p up to 4K, plus 8K and 120fps on Business tiers. There is no separate per-conversion fee.
